I don't want businesses I have no involvement with contacting me out of the blue. It's not quite spam...
Unsolicited email from parties you have no involvement with is spam by definition.
And note to spammers and marketers on HN, I know I'm abusing my spam filters, but if I see emails from parties I don't recognize because "I subscribed for updates to one of their partners" (or some other bullshit explanation like that), I instantly flag them as spam, even if they have an unsubscribe button, because I can't unsubscribe from something I never subscribed to and I refuse to validate my email address like that.
The easiest way of killing spam is to hit the spam-button in Thunderbird. Spam is always spam and I have more fun things to do than find some unsubscribe button. That will only mark my email as active and give a better price when selling it further.

It's even more fun doing it in GMail, because if enough other people do it then spam is more likely to be widely dealt with in the manner it deserves.
You can create a filter for the word "unsubscribe" if you're feeling dangerous
